MAGAZINE FIRE-ARM.

SPECIFICATION formingpart of Letters Patent No. 413,196, dated October22, 1889.

Application tiled November 28, 1884. Serial No. 148,992. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN M. MARLIN, of New Haven, in the county of NewHaven and State of Connecticut, have invented a certain new and usefulImprovement in Magazine Fire-Arms, of which the following is aspecification.

My invention relates to magazine fire-arms; and it consists in certainimprovements in the magazine and connections therewith, substantially ashereinafter described and claimed.

In the drawings, Figure 1 is a side view of the barrel and magazine of afire-arm, partly in section. Fig. 2 is a view of the magazine andmagazine-case detached from the arm, partly in section, and broken awayto show the internal construction. Fig. 3 is a view of the muzzle end ofthe arm with the magazine inserted in its case before it is locked.Fig.4 is a side view of the same from one direction. Fig. 5 is a sideview of same from another direction. Fig. 6 is a side view of the sameafter the magazine has been turned and locked in its case. Fig. 7 is anend View of same. Fig. 8 is a section through the line A A of Fig. 1.Fig. 9 is a side View in section of a portion of Fig. 1 from a differentdirection than is shown in that figure.

My present invention is an improvement upon the mechanism shown in myapplication filed in the Patent Office August 4, 1884, No. 139,587.

B is the barrel of the arm.

is the magazine-case.

D is the magazine,which is removable from the case to fill the same withcartridges. This magazine is constructed to be filled and inserted inthe case and revolved a part of a turn, which unlocks the sliding bolt(1 from the notch d by bringing the head of the bolt d against theinward projection d in the magazine-case, and allows the bolt (1 toslide along the groove (1 substantially as described in my formerapplication. This allows the spiral spring (i to force the bolt dagainstthe cartridges and force them from the magazine in the ordinary manner.

In order to prevent the cartridges from escaping from the magazinebefore it is seated in its bearings in the magazine case and while it isbeing introduced thereimlprovide a sliding sleeve eon the end of themagazine, to which is attached a spring a, which projects through a slotinto the magazine when the sleeve 6 is shoved toward the open end of theformer, as shown in Fig. 9, and in this position the end of the springforms a stop to prevent the cartridges from escaping. When the magazineis pressed downward into its case, as shown in Fig. 1, the shoulder 6comes against the end of the sleeve 6 and crowds it toward the muzzle ofthe arm, thus withdrawing the spring 6 from the magazine and allowingthe cartridge to escape from the open end thereof.

In orderto lock the magazine in-place when it is revolved so as to bringits head 0 into the groove 0, as described'in my said formerapplication, I provide a latch 0 which is pivoted in the head end of themagazine, as shown in Fig. 2, upon a pivot 0 passing through a slot 0 inthe latch, and the latch is held outward by a spiral spring 0 I nextprovide in the magazine-case C at the muzzle end of the arm an L-shapedslot m, so constructed that when the magazine is first inserted into thecase the latch 0 will enter this slot in the position shown in Figs. 3,4, and 5, and be crowded inward upon the spiral spring 0 but when themagazine is turned to the position shown in Figs. 6 and 7 the shoulder 0upon the latch 0 will be pressed by the spiral spring 0 outward into thehorizontal part of the L-shaped slot m, as shown in the last-namedfigures, and will thus prevent the magazine from being revolved backwardso as to release its head 0 from the slot in the barrel 0 by anyaccident.

When it is desired to remove the magazine from its case, by simplypressing inward with the thumb upon the projecting part of the latch 0until the shoulder is withdrawn from the L-shaped slot the magazine maybe revolved backward until its head is released from the slot 0, when itcan be withdrawn from its case.

It will be observed that the spring-stop e and the latch c automaticallyoperate in conjunction and by the same movements of the magazine ininserting itinto its case, and when the magazine is locked in place atthe muzzle end of the arm, as described, the

spring-stop e is thereby prevented from entering the bore of themagazine by any accident. It will also be observed that the samemovements which automatically lock the magazine in place by the latch cunlock the bolt (1 from the notch d automatically.

What I claim as new and of my invention l. The combination of theremovable magazine D, the sleeve 6, having stop e attached thereto, andthe shoulder 6 located in the magazine-case C in the path of sleevecwhenthe magazine is introduced into the case, and adapted to be brought intocontact With and move the sleeve and stop When the magazine is insertedin its case, substantially as described.

2. The combination of the removable magazine D, provided With the latch0 attached thereto, and the head 0, projecting laterally therefrom, withthe magazine-case provided with the slot on, and the barrel of the arm,provided with the slot 0', said slots on and 0 being respectivelylocated and adapted to engage with said latch and head of themagazine,substantially as described.

3. The combination of the magazine-case 0, provided With the slotm andstop (1 projecting inwardly, the removable magazine D, fitting withinthe case and provided with the slot (1 and stop-notch d, the spring dand the sliding bolt (1 Within the magazine, provided with a headadapted to engage With notch d to lock the same and with stop (Z tounlock the same, and the latch 0 adapted to lock said magazine and itscase together substantially as described.

at. The combination of the magazine-case O, provided With the shoulder eand slot m,with the removable magazine D, provided with the slidingsleeve 6, adapted to engage with said shoulder and the stop 6, and thelatch 0 adapted to lock said magazine and case together by engaging slotm, substantially as described.
